Dresden 2, Exelon’s 867-megawatt reactor 25 miles southwest of Joliet, returned to full power from 61 percent of capacity yesterday.
The 1,065-megawatt Clinton 1 plant, 23 miles southeast of Bloomington, rose to 96 percent of capacity from 76 percent and Quad Cities 1, a 867-megawatt unit 20 miles northeast of Moline, was at full power today compared with 99 percent yesterday.
